hit the windows key, then type device manager
. click on the display adapter
, right click on the radeon HD 7700 Series device (it won't say 7770, it will just be 7700), uninstall all of them. look for anything with a yellow ?
if there is anything with a yellow ? you know there are uninstalled devices. either way we'll assume there is a driver issue at play. go to gigabyte's webpage, look up your 990fxa-ud3
, download the latest driver for EVERYTHING. install it all. get the bios update, update the bios.
restart your computer and install the latest whql radeon driver for your graphics card. see how your hardware behaves. if you still are drawing terrible fps, download hwmonitor, and gpuid, install both, get the furmark benching software, run all 3 programs and watch your gpu's behavior. watch the temps mostly. watch the voltages... we need to make sure the hardware is working right. assuming no issues (take a screenie with all 3 windows open, post it here) we'll go forward with the troubleshooting at that point.
